Continuation of application Serial No. 548,376, filed March:31, 1922. This. application filed June 4, 1925.

' Serial 110.34. 980.

This invention relates to a hydraulic fishing boat and has for its principal Ob ect to provide .a novel and improved means posi-.

tion'ed within the interior of a vessel for trapping fish as the same proceeds upon its course. 4 A e This application is a continuation of application Serial No. 5 18376, filed March 31, 1922.

One of the objects of my invention is to provide a vesselwith a longitudinally extending tube positioned with the interior of the same and extending from the bow to the stern including anovel and improved net which may be raised. and lowered to the required depth from the bow of the vessel so as to trap the fish especially when proceeding against current and. in the path of a school of fish. p A continued object of my invention is to provide a hydraulic fishing boat of the size and character used in deep sea fishing wherein the vessel is provided with sectionaltube extending ironr the lower portion' of the bow, rearwardly and upwardly to the stern, including a novel and improved adjustable net at the front end of said tube and a fishing trap at the: rear end of the tube. 1

To enable others skilled in the art to fully comprehend the underlying features of my invention that they may embody the same in. the various modifications in structure and relation contemplated, drawings depicting a preferred form have been annexed as a part of this disclosure and in such drawings, similar reference characters denote corresponding parts throughout all the views, of which, v p )1 Figure his a perspective view showing the vessel and the position of the tube with respect to the front net and rear trap.

, ,Reterringnow to the drawings, wherein like reference characters designate corresponding parts-throughout all the views, 5 designates in. its entirety a conventional type of sailing vessel preferably driven by Diesel engine so as not to cause disturbance in fishing waters. Within the vessel. '1 have provided the scctionalttube (5 'vvhich extends downwardly from the main deck 7 and substantiallyhorizontal as indicated at 8 near the front or how of the vessel. The rearward end 9 of the tube is also disposed substantially horizontal with the deck and leads to-a trap 1O permittingthe waterto flow overboard and trap the fish as the same are driven upwardly through the tube in the manner subsequently to be described. Thetube is preferably constructed of a plurality oi sections so that the same may be replaced or easily "repaired and to that purpose. I have provided a manhole 11 in one oi said sections so that access may be gained tothe interior of the tube. The section 12 containing the manhole 11 is further provided with a nozzle 13' in communication with a pipe or lead let connected to a centrii'ugalpump 15 so that as the water flows into the'tube, the same may be forced upwardly and consequently decrease the re sistance offered by the watertrapped in the tube during, the progress of the vessel. The restricted opening 15 of the nozzle coininunicates with a throat 16 in the section adjacent the section 12 thus causing a swift current and effectively forcing the water a. upwardly tothe deck of the'vessel.

The section 17 of the tube is provided with a gate valve 18, which may be raised and lowered in any well known manner from the deck when it is desired to exclude water from the tube as when sailing under norn'ial conditions and the front net is raised. Al Y-shaped connection 20 at the front end of the tube 6 is disposed so as to cause the fish entering the front net to enter the tube and the suction created by the centrifugal force will causethe fish to pass upwardly in the current and stream to be discharged into the trap 10.

v vThe rear section 22 of the catching net is tormedi'of a tubular frame 2%, the sides and bottom of which are connected by a strong wire mesh which is of suflicient strength to resist any tendency to dislodge it from its position. The front section frame 23 of the net is pivotally connected as at. 24: to the front edge of the frame 22 and is adopted to swing, on-the guide rail 25 through the 'medium of an extension 25 on the frame 23, when the said front section is raised and lowered by the cables 26 leading to the deck of the vessel and the front section of the net is shown in its elevated position with dotted lines on Figurel. The rear frame 22 of the net is further provided with arod 25 having a roller 26 on the bottom thereof, which engages the sloping bottom of the vessel, the bottom acting as a wedge to maintain the net in rigid position against a plate 27 when the cables 28 are drawn upon. By releasing the cables 28, the sections 22 and 23'may be raised as an entirety by cables 26*, in which instance the roller 26 will ride along the bottom or bow of the vessel and consequently, the entire net will be raised from the water. It will also be observed that the net is ofsnch a length as to extend considerably below the bow of the vessel to meet an oncoming school of fish and that the front net section 23 may be raised and lowered to the desired degree as fishing necessities may require.

"While I have illustrated and described my invention with some degree of particularity, I realize that inpractice various alterations therein may be made. I therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlated parts without departing from the spirit of the invention or the scope of the appended claims... I

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is 1. In combination, a boat, a tube extending longitudinally through the boat terminating at its bow andstern, a pump, an outlet from the pump situated in the tube intermediate its ends, said outlet'forming a suotion means for forcing the water rearwardly through the tube whereby resistance to progress of boat is decreased, and a for aminous trap mounted at the stern end of said tube.

2. In combination, a boat, a tube extending longitiulinally through the body of the boat, said tube being partially below the water level. line, a trap at the stern and opposite end of the tube and means within said tube to force the water rearwardly and decrease the resistance offered during the progress of the boat. I 3. In rombination, a boat, a tube extending longitudinally through the body of the boat, the major portion of said tube being normally below the water level line, a trap at the'stern end of the tube but above the said normal water level line, and suction means within said tube to force thewater rearwardly and decrease theresistanceoffer-ed during the progress of the boat.
